INA180B4IDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Non-inverting current-sense amplifier input. For high-side sensing, connect to the bus/supply side of the sense resistor; for low-side sensing, connect to the load side of the sense resistor. Common-mode range -0.2 V to +26 V, independent of VS. |
| 2 | GND | power_in | Analog ground reference for the amplifier and output stage. Connect to system analog ground. |
| 3 | IN- | input | Inverting current-sense amplifier input. For high-side sensing, connect to the load side of the sense resistor; for low-side sensing, connect to the ground side of the sense resistor. |
| 4 | OUT | output | Buffered voltage output. Output voltage equals the sensed differential input voltage multiplied by the fixed gain of 200 V/V (A4 device). Slew rate 2 V/µs; drives ADC or comparator inputs. |
| 5 | VS | power_in | Positive power supply, 2.7 V to 5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin. Quiescent current 260 µA (max, INA180). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
